Description
Technical Field
[0001] This utility model belongs to the field of metal clamping technology, specifically a welding clamp that is easy to adjust. Background Technology
[0002] Welding fixtures consist of machines, units, and mechanisms. Fixtures are commonly used in metal processing or pump body and bridge housing grinding operations. Their main function is to fix and stabilize the metal to be welded. Fixtures fix metal parts on the worktable surface and perform operations according to requirements. Fixtures refer to devices used in mechanical manufacturing processes to fix the workpiece in the correct position for construction or inspection. They are also called clamps. In a broader sense, any device used to quickly, conveniently, and safely install workpieces in any step of the process can be called a fixture.
[0003] In existing technologies, welding fixtures are typically used to fix metal parts during operation, requiring mechanical processing. Clamping devices are commonly used in this process, and their applications are quite extensive. A clamping and fixing device usually involves feeding the metal part into the jaws of the clamping device for fixation. Welding operations are then performed after the jaws are secured. A typical clamping device consists of a frame, motor, clamping plates, handwheel, boom, connecting rod, lead screw, and welding laser. Rotating the handwheel drives the adjustment shaft to adjust the height and lateral position of the clamping device, which in turn adjusts the position of the upper jaws. The clamping plates at the ends then engage to complete the fixing and clamping operation of the metal part.
[0004] In current technology, the clamping and fixing devices for polishing machines on the market typically consist of a frame, motor, clamping plate, slide rail, handwheel, boom, connecting rod, lead screw, and welding laser. Rotating the handwheel drives the adjustment shaft to rotate, adjusting the height and lateral position of the clamping device, which in turn adjusts the position of the upper gripper. The clamping plate at the end cooperates to complete the fixing and clamping operation of the metal parts. However, during the welding clamping process, the clamping device often needs to adjust the position of the clamps for metal parts of different specifications to prevent collisions between the parts and the welding laser. This is time-consuming and labor-intensive, thus affecting work efficiency. Therefore, to address the above problems, an easily adjustable welding clamp is proposed. Utility Model Content

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0022] Please see Figure 1-5 As shown, an easily adjustable welding fixture includes a clamping base 16. A clamping bracket 15 is mounted on the surface of the clamping base 16. Two sets of central retaining springs 23 are mounted on the middle surface of the clamping bracket 15. Two sets of connecting rods 33 are threaded through the middle of the central retaining springs 23. A transverse synchronous handwheel 21 is fitted to the end of the connecting rod 33. A transverse lead screw 22 is fitted to the middle of the transverse synchronous handwheel 21. A three-axis adjusting seat 18 is fitted between the transverse synchronous handwheel 21 and the central retaining springs 23. The bottom of the three-axis adjusting seat 18 is fitted with... A vertical synchronous handwheel 24 is installed, with a vertical lead screw 17 mounted in the middle of the handwheel 24. A motor mounting plate 27 is mounted on the top of another set of connecting rods 33. Two sets of gaskets 31 are mounted on one side of the motor mounting plate 27. A motor base 30 is mounted on the surface of the gaskets 31. A motor 28 is mounted on the top of the motor base 30. A first rotating wheel 20 is mounted on the output end of the motor 28. A second rotating wheel 19 is mounted on the other side of the motor mounting plate 27. The first rotating wheel 20 and the second rotating wheel 19 are connected by a transmission belt.
[0023] In operation, current market-ready grinding and polishing machine clamping and fixing devices typically consist of a clamping bracket 15, a motor 28, an end clamping plate 26, a synchronous handwheel, a boom 32, a connecting rod 33, a lead screw, and a welding laser 3. Rotating the synchronous handwheel drives the adjustment shaft to rotate, adjusting the height and lateral position of the clamping device, thereby adjusting the position of the upper end clamping device. The end clamping plate 26 then cooperates to complete the fixing and clamping operation of the metal parts. However, during the welding and clamping process of metal parts, the clamping device often needs to be adapted to different specifications of metal parts. The position of the component is adjusted to prevent it from colliding with the welding laser 3. However, this is time-consuming and labor-intensive, which affects work efficiency. Therefore, to address the above problem, an easily adjustable welding fixture is proposed. When performing welding clamping operations on metal parts, the lower horizontal synchronous handwheel 21 is rotated, which in turn drives the middle horizontal lead screw 22 to rotate synchronously. When the horizontal lead screw 22 rotates, the three-axis adjustment seat 18 will cooperate to adjust the horizontal position, which in turn drives the upper clamping device to adjust the position synchronously, thereby completing the horizontal clamping adjustment of the metal part.
[0024] Furthermore, a limiting wheel 29 is mounted below the second rotating wheel 19, and a large arm 32 is mounted in the middle of the limiting wheel 29. An end clamp 26 is installed on the side of the large arm 32, and an elastic retaining ring 25 for the shaft is mounted on the surface of the large arm 32. A foot pad 14 is mounted below the clamping base 16, and a welding frame 13 is mounted on the other side of the clamping base 16. Four sets of casters 4 are mounted below the welding frame 13, and a lower support 5 is mounted in the middle of the welding frame 13. A vertical adjustment shaft 8 is provided, with a first handwheel 9 installed at one end of the vertical adjustment shaft 8. A vertical chuck 6 is installed in the middle of the vertical adjustment shaft 8. A horizontal adjustment shaft 12 is installed in the middle of the tip of the vertical chuck 6. A second handwheel 7 is installed at one end of the horizontal adjustment shaft 12. A horizontal chuck 11 is installed at the other end of the horizontal adjustment shaft 12. A fixed connecting plate 10 is installed on the surface of the horizontal chuck 11. A power distribution box 1 is installed on the inner wall of the fixed connecting plate 10. A welding laser 3 is installed at the top of the power distribution box 1.
[0025] During operation, parts of different specifications are often encountered in welding. When encountering larger parts, the position of the laser needs to be adjusted to prevent collisions during operation. By rotating the No. 2 handwheel 7 installed in the middle, the lateral adjustment shaft 12 will repeatedly extend and retract, thereby driving the fixed connecting plate 10 installed at the end to move laterally. When the fixed connecting plate 10 moves, it will drive the laser welding device installed on the surface to change its lateral position synchronously. At the same time, the rotation of the No. 1 handwheel 9 can adjust the vertical height of the laser welding device, thereby completing the laser welding clamping operation of the entire metal part.
[0026] Working principle: In current technology, the clamping and fixing devices of polishing machines on the market typically consist of a clamping bracket 15, a motor 28, an end clamping plate 26, a synchronous handwheel, a boom 32, a connecting rod 33, a lead screw, and a welding laser 3. Rotating the synchronous handwheel drives the adjustment shaft to rotate, adjusting the height and lateral position of the clamping device, thereby adjusting the position of the upper end clamping device. The end clamping plate 26 then cooperates to complete the fixing and clamping operation of the metal parts. However, during the welding clamping process, the clamping device often needs to adjust the position of the clamp for different specifications of metal parts to prevent collisions between the parts and the welding laser 3. This is time-consuming and labor-intensive, affecting work efficiency. Therefore, to address the above problems, an easily adjustable welding clamp is proposed. When performing welding clamping operations on metal parts, rotating the lower horizontal synchronous handwheel 21 drives the middle... The transverse lead screw 22 rotates synchronously. When the transverse lead screw 22 rotates, the three-axis adjusting seat 18 will adjust its transverse position accordingly, thereby driving the clamping device above to adjust its position synchronously, thus completing the transverse clamping adjustment of the metal part. In welding operations, parts of different specifications are often encountered. When encountering larger parts, the position of the laser needs to be adjusted to prevent collisions during operation. By rotating the second handwheel 7 installed in the middle, when the second handwheel 7 rotates, the transverse adjustment shaft 12 will repeatedly extend and retract, thereby driving the fixed connecting plate 10 installed at the end to move its transverse position. When the fixed connecting plate 10 moves, it will drive the laser welding device installed on the surface to change its transverse position synchronously. At the same time, when the first handwheel 9 rotates, the vertical height of the laser welding device can be adjusted, thus completing the overall laser welding clamping operation of the metal part.
